CAMP STOVE.

Application filed July 7,

tion and which will therefore withstand rough usage. It is a furtherobject to produce a stove that can be conveniently primed and in whichneither the burners nor the tank has to be moved during the primingoperation. It is a still further object to produce a stove having. animproved wind break and another object is to produce a valve mechanismof novel construction by means of which the priming operation can beconveniently controlled.

The above and other objects that may be come apparent as thisdescription proceeds, are attained by means of a construction and anarrangen'ient of parts that will now be described in detail andreference for this purpose will now be had to the accompanying drawingsin which the preferred embodiment of the invention has been illustratedand in which:

My stove comprises a casing having a bottom 1, a side member 2 and ends3 and 4-. The side opposite side 2 has been indicated by numeral 4: andis lower than the side 2. The ends 3 and 4 are bent so as to provideshort portions 5 and 6 which are secured to the side 4 in the mannershown in Fig.1. Extending longitudinally of the casing and parallel withthe sides 2 and 4 is a hollow partition. In 3 this partition has been.shown in cross sections and is formed of a like that shown in Fig. 2.This grate is se- 1927. Serial No. 263,927.

pieceof sheet metal having sides 7 and 8 which are connected at theirupper ends in such a way as to form a rabbet 9 that ex tends the entirelength of the partition. The lower ends of sides 7 and 8 are bentoutwardly at right angles in the manner indicated by, numeral 10 andthese ends rest on the upper surface of bottom 1. The bottom of thecasing has been pressed upwardly so as to form an elongated narrow ridge11 whose width is equal to the distance between the sides 7 and 8. Thisridge projects upwardly into the partition and provides an obstructionwhich prevents gasoline from flowing from one side of the partition tothe other. Tongues 12 are stamped out of the bottom 1 and are bent overthe outwardly projecting flanges 10 so as to hold the partition inplace. The ends of thepartition members 7 and 8 are also provided withoutwardly extending flanges 13 which are engaged by tongues 12 in themanner shown in Fig. 3. The ridge 11 is provided with a plurality ofopenings 14 and the upper end of the partition is provided with aplurality of openings 15 (Figs. 1 and 2). A grate comprises a pluralityof U-shaped members 16 which are spotwelded to parallel bars 17 so as toform an assembly cured to the side 2 by means of hinges 18 and has itsopposite side resting in the rabbet 9.

.Fastened to one of the sidemembers of the U-shaped member located atthe left (Fig. 2) is a baiiie plate 19. This baiile plate has its centerportion cut out so as to form an opening 20 (Fig. The function of thisbaffle plate will appear as the description proceeds. Secured to theupper surface of the bottom member 1 is a manifold 21 to each end ofwhich is connected a burner 22. The manifold 21 has a mixing chamber 23that extends upwardly to a point above and adjacent to the left handburner (Fig. 2). The burner assembly is secured to the bottom member 1by means of brackets 24.

Between the hollow partition and the side a is a chamber within which islocated gasoline tank 25. This tank is held in place by means of a clamp26, and is provided at one end with a pipe 27. This pipe connects thetank with a valve which has been indi cated as a whole by numeral 28. Agenerator tube 29 has one end connected with the duplex valve 28 andextends over the adja tion, controls the opening through the gen eratortube29. Valve'handle 31is connected with the valve stem 32 by means ofafunie versal joint 33, which permits the handlevtol be swung inwardlyinto the box or to be moved to'the position shown in Fig. 2. The.

tank25 is providedwith a fill opening" 34 which is controlled by meansoi a pl-ug "to-function, it is, of course, necessary that Tank'25 isadapted tocontain gasoline and air under pressure. J \Vhen the valve 30is open gasolinefwill flow from the tank into and through the generatortube 29.: ""l Vhen the burner is operating the "heat will vaporize thegasoline in the generator tube so, that only'vapor' will enter themixing chamber 23. Before the stove can be made i the generator tube '29shall be heated to such a temperature-that the gasolinewithin thesame'i'vill be converted into vapor. In order to heat the generatortube, I-have provided the distributor plate'of burner 22 with a primingcup or central depression 36,"which is-adapted to receive-1a quantity ofgasoline \vlllCllymity'bfi ignited and wh chserves to heatthergeneratortube 29. V

V Difli'cu'lty has heretofore beenexperieiicd in providing suitablemeans for conducting gasoline; from the tank" 25 to 'thejpriniing, cup36, andithas been customary to have the,

tank 25 with its attached generator tube detachable from the casing,sotha-t the endof'the generator tube can be brought into or above thepriming cup 36 in orderto dep osit gasoline therein. In m construction,the

' tank 25 is securely fastened to the casing and consequently; thegenerator tube 29- is also, stationary: For the purpose of transferringgasoline to'thepriining cup, I have provided" a duplex valve structurewhich'has beerr'indicated asa whole by numeral 28. This duplex valvecomprises two valves, one of which 1 has been indicated by numeral 30andwhlch comprises the-valve stem '32. This controls thefiow of gasolinefrom the pipe 27"to the generator tube 29, (Fig. 5). Extending from theopening intowhich the pipe'27 is secured tothe valve which controls theflow of 'gasoline to the'priming tube 37 is an opening 38. This openingterminates underneath the valve seat with which the valve stem 39co-;

operates." This valve stemhas a threaded portion l0 *(Figs. 6, 7 and 9)andis provided an openinginto which one end of the prim-- -with a handle41 by Ineansof whichit can berotated sons to open and close the valve.An opening 42 extends from thevalve chamber in which the valve stem 39is locatedto ing tube 37 is inserted (Fig. 6). WVhen valve stem 391srotated so as to open the passageway troin the openmg 38 to the opening42,

gasolinewill 'fiow from the tank into pipe 37 and into thepriming cup36. After the pri1ning cup has been filled with gasoline valve 39 isclosedand thegasoline in the priming l.

cup ignited. The capacity of the priming cup. is SllCl'lltllELll whenthe gasoline which it will contain has been consumed, the generator;tube. 2S-will have-been heated suilicientl y to convert the gasolinetherein to vapor anditherefore when valve30 is open, gasoline will passinto the generator tube and be comevaporized and flow through the mix- IV and through the manifold 21-andoutthrough the openlngs in thedistributor; plate ofthe burner. lhis gaseous ing chamber 23 mixturewill' then'ignite' and burn 'with a 7 blue flame which will continue tokeep the generatoi tube 29 heated. The .flow of gaso-' line to theburnershownat the right in Fig. 2is controlled by a valve 43.

' In the embodiment shown in Figs; 5'and Gfthepipe 37*l1as been shown assecured to the-duplex valvestruc'ture by means of set screw 44.- Thispipe37 is thereforestationary' and-willzreinain in'the position shownin- Fig. 2. Owing to'theffact that pipe 37 is; empty during the burningof the'stove,

it'becomes very highly heatedwith the re sult that after long use ithasto'be replaced by a new one; this can readily be done by and withdrawingloosening the set screw it the old pipe. v

In Figsa8and 91 have shown a slight modification which is so constructedthat the priming tub e 37?: which correspond'st-o the prim.-

ing tube 37in the l'otherfigures, has its end 45' bent-atright angles inthe manner shown in- Fig. 9. This end projects upwardly through anopeningtliat intersects opening 42 at right angles and is held in placeby means o'fa screw 46. The priming tube 37? can be rotated -fro1nfullline to dotted line position, (Fig. 8); When-it is in full lineposition, the hole 4L7 registers withthe; open ing 42 and" when valve 39is open gasoline will flow through th'is'tube into the priming cup 36.Afterhuflicient gasoline'has been transferred tothe priming cup thetube" is moved into the' dotted line position so {as to be out of thezone of the fire and will therefore be kept from becoming li eatedtosuchan-extentthat it will be destroyed.

In FigQtI have indicateda modification burnencompartment to the tankcompartment. Ordinarily,therewill be no gasoline In other respects thisconstruc- V in either of these compartments, but some- 1 times ithappens that the operator is negli-- gent and permits thefgasolineto"overfiow' when he fills the priming cup. When this happens, some of thegasoline'may flowinto the'chamber' containing the tank and becomeignited when they-burneris" ignited. The" burning of gasoline around andabout the tank 25 would have a tendency to raise the temperature to sucha high point that an explosion might occur. With the construction shownand described, this danger is obviated.

A cover member 18 is hinged to the upper edge of the side 2 and thismember has secured to it three other pieces which have been indicated bynumerals 19, 50 and 51. The parts designated as as and 50 are secured tothe cover by means of hinges 52. l/Vhen the cover is in open position,the end members 19 and 50 are swung outwardly into the position shown inFigs. 1 and :2 and rest on the projeetingfingers 53. The part marked 51is hinged to the outer edge of the cover and rests upon the upper endsof members 19 and 50 when the parts are in the position shown in Fig. 1.The side 51 is adapted to extend down between the tank and the partsmarked 4, 5 and 6, and serves to completely enclose the parts when thecover is moved to closing position. The side 51 is provided with ahandle 54: by means of which the stove may be carried. The stove isprovided with two legs 55 of a well known construction that serves tosupport the stove when it is in operative position and which will holdthe cover from opening when the parts are folded for transportation.

The parts to which the invention relates in the present application areembodied in the duplex valve construction by means of which the primingcup can be filled with gasoline without moving the tank and in whichthis valve is also protected from the flame by means of the baflie plate19. In addition to this the ridge 11 is a feature that is novel in astove of this type. I also wish to call attention to the assemblycomprising the cover member 18 and parts 49, 50 and 51 which form anexcellent wind break and in which the part 51 cooperates with the coverso as to entirely enclose the gasoline tank during transportation.

Having described my invention What I claim as new is:

1. A camp stove comprising, in combination, a casing having two ends,two sides and a bottom, the bottom having an upwardly extending ridgeextending from one end member to the other, said ridge being parallel tothe sides, a hollow partitionextending along the ridge so as to dividethe easing into two compartments, a burner assembly in one compartment,a fuel tank in the other compartment and a conduit extending from thefuel tank to the burner assembly.
